Largay (left in photo) was last seen in July hiking the Appalachian Trail in Maine, in the Franklin County area. An intensive search for Largay, 66, of Tennessee, failed to find any trace of her.

Largay started hiking the trail at Harper's Ferry, West Virginia, in April, intending to end the journey at Maine's Baxter State Park. She was in frequent contact with her husband, George, who provided her with supplies at predetermined stops along the way.

On July 21, Largay was resupplied and resumed her hike on a part of the trail near the town of Rangeley, and later texted her husband that she was on top of Saddleback Mountain. She stayed at a lean-to in Redington Township that night, intending to meet her husand two days later. She never arrived.

A 9-day search with aircraft, dogs, horses, ATV's and hundreds of volunteers yielded no sign of her. Subsequent searches have also turned up nothing.

Largay, whose trail name is "inchworm," was last seen wearing a reddish colored pullover shirt, tan shorts, a blue hat and a black and green backpack.
